Laboratory bounds on Lorentz symmetry violation in low energy neutrino physics
Abstract
Quantitative bounds on Lorentz symmetry violation in the neutrino sector have been obtained by analyzing existing laboratory data on neutron beta decay and pion leptonic decays. In particular some parameters appearing in the energy-momentum dispersion relations for nu_e and nu_mu have been constrained in two typical cases arising in many models accounting for Lorentz violation.Keywords
